Economics of operation of 38' G.R.P. fishing vessels issued by the A.D.B. Fisheries Project: a case study

The author gives a financial and economic valuation of the operation of vessels in the 38 foot GRP class. He discusses particularly the materials and methods of fishing they use, species composition of their catches, their rate of return, break-even analysis, financial and social analysis.

Phylogenetic implications of the 38 putative ancestral chromosome segments for four canid species

Chromosome homologies between the Japanese raccoon dog (Nectereutes procyonoides viverrinus, 2n = 39 + 2-4 B chromosomes) and domestic dog (Canis familiaris, 2n = 78) have been established by hybridizing a complete set of canine paint probes onto high-res

婴猴麻疹38例临床分析

麻疹病毒是副粘病毒科麻疹病毒属成员之一,主要通过呼吸道传播,其传染性强,人群发病率很高,主要常发于婴幼儿及儿童[1].国外有报道人源麻疹病毒和狗的犬温热病毒可引起捕获猕猴麻疹病毒感染的暴发[2-4],并表现为与人相似的临床症状和病理表现[5-6].目前,国内还未有猕猴麻疹暴发的病例报道.本中心2008年1月至3月共有38例8月龄~15月龄的腹泻猕猴诊断为麻疹,经过及时确诊,有效治疗,临床效果很好的.分析如下.

200-V lateral superjunction LIGBT on partial SOI

This letter presents a novel lateral superjunction lateral insulated-gate bipolar transistor (LIGBT) in partial silicon-on-insulator (SOI) technology in 0.18-μm partial-SOI (PSOI) high-voltage (HV) process. For an n-type superjunction LIGBT, the p-layer in the superjunction drift region not only helps in achieving uniform electric field distribution but also contributes to the on-state current. The superjunction LIGBT successfully achieves a breakdown voltage (BV) of 210 V with an R dson of 765 mΩ ̇ mm 2. It exhibits half the value of specific on-state resistance R dson and three times higher saturation current (I dsat) for the same BV, compared to a comparable lateral superjunction laterally diffused metal-oxide-semiconductor fabricated in the same technology. It also performs well in higher temperature dc operation with 38.8% increase in R dson at 175°C, compared to the room temperature without any degradation in latch-up performance. To realize this device, it only requires one additional mask layer into X-FAB 0.18-μm PSOI HV process. © 2012 IEEE.

Si_(0.75)Ge_(0.25)虚衬底上应变补偿Si/Si_(0.62)Ge_(0.38)量子阱发光

由于Si/SiGe异质结构的带阶差主要发生在价带,为实现高效率的发光,本文从理论上设计了在硅基Si_(1-x) Ge_x虚衬底上外延应变补偿的Si/S_(1-y) Ge_y(y>x)量子阱的能带结构,将量子阱对电子的限制势垒提高到100meV以上.在实验上,采用300℃生长的Ge量子点插入层,制备出薄的SiGe驰豫缓冲层(虚衬底),表面Ge组份达到0.25,表面粗糙度小于2nm,驰豫度接近100%.在我们制备的SiGe缓冲层上外延了应变补偿SiGe/Si多量子阱结构,并初步研究了其发光特性.

封育对科尔沁沙地小叶锦鸡儿群落植被特征及空间异质性的影响

以科尔沁沙地小叶锦鸡儿群落为对象,分析了放牧和不同封育年限下小叶锦鸡儿群落的植被特征及植被分布的小尺度空间异质性。结果表明:放牧和封育样地内植被均以1年生草本植物为主,物种数没有明显差异;封育6年、封育12年样地的植株密度分别为(124.46±5.22)株.m-2和(203.05±10.38)株.m-2,显著高于放牧样地(P<0.05);封育样地的Shannon-Wiener多样性指数、Simpson多样性指数、Pielou均匀度指数均低于放牧样地,并随着封育年限的增加而减小;封育样地植被分布的小尺度空间异质性小于放牧样地,并且封育年限越长,空间异质性越小。

Megiston agathon (Pl. Ap. 38 a) – Sedno życia i filozoficznego wyzwania Sokratesa

We suggest a certain minimal approach to the historical Socrates on the basis of Plato’s Apology. This text makes it possible to reconstruct the authentic charge and the defense line of Socrates, as well as his motivation and the quintessence of his philosophical challenge. The most important thing is what the philosopher says in the face of his death sentence: that the greatest good for a man is to live an examined life focusing on virtues and ethical values. Unfortunately, the preponderance of studies, even the most recent ones, fail to recognize the philosopher’s provocative challenge, whilst it is not only a crucial motif in the Socratic examining (ἐξετάζειν), i.e. testing the interlocutors’ knowledge by means of irony, elenchos and aporia, but also an inspiration for his direct and indirect followers in seeking virtues and the greatest good.

De la cooperativa agroalimentaria a la "learning netchain". Hacia un planteamiento teorico interorganizativo e interpersonal

Se propone un planteamiento teórico/conceptual para determinar si las relaciones interorganizativas e interpersonales de la netchain de las cooperativas agroalimentarias evolucionan hacia una learning netchain. Las propuestas del trabajo muestran que el mayor grado de asociacionismo y la mayor cooperación/colaboración vertical a lo largo de la cadena están positivamente relacionados con la posición horizontal de la empresa focal más cercana del consumidor final. Esto requiere una planificación y una resolución de problemas de manera conjunta, lo que está positivamente relacionado con el mayor flujo y diversidad de la información/conocimiento obtenido y diseminado a lo largo de la netchain. Al mismo tiempo se necesita desarrollar un contexto social en el que fluya la información/conocimiento y las nuevas ideas de manera informal y esto se logra con redes personales y, principalmente, profesionales y con redes internas y, principalmente, externas. Todo esto permitirá una mayor satisfacción de los socios de la cooperativa agroalimentaria y de sus distribuidores y una mayor intensidad en I+D, convirtiéndose la netchain de la cooperativa agroalimentaria, así, en una learning netchain.
